Pechell was the second son of the Rev. Horace Robert Pechell (1792-1882),
Fellow of All Souls, and rector of Bix, near
Henley-on-Thames, by his wife Lady Caroline Mary Kerr (d.1869), daughter of
Lord Mark Kerr and
Charlotte McDonnell, Countess of Antrim. He joined the
Royal Navy, and served in the
Baltic Expedition of 1854-55, when an Anglo-French fleet entered the Baltic sea to attack the Russian naval base of
Kronstadt during the
Crimean War. Pechell was in command of the
gunboat at the bombardment of
Sveaborg. He died at his residence in
London on 9 July 1902. Pechell married, in 1861, Ellen Maria Derby (d.1908), daughter of Cobbett Derby and niece of
Sir Samuel Fludyer. The couple left nine children, including Captain Mark Horace Kerr Pechell (1867-1899) and Captain Charles Augustus Kerr Pechell (1869-1899), who both died a couple of days apart in
South Africa during the early days of the
Second Boer War. The youngest daughter, Aileen Kerr Pechell (ca 1879-1920), was the wife of
Sir Arthur Russell, 6th Baronet. Another daughter, Maud Louisa Pechell, was the mother of
Mark Ogilvie-Grant by her marriage to the ornithologist
William Robert Ogilvie-Grant. ==References==
